Allocation of network resources based on antenna information and/or device type information

ABSTRACT

A device may receive a request, from a user equipment (UE), to connect to a network. The device may receive antenna information indicating that the UE has a single antenna, and the device may receive device type information indicating a device type of the UE or network resource requirements associated with the UE. The device may obtain network policy information, relating to the UE, based on the antenna information and/or the device type information. The network policy information may indicate one or more policy rules associated with allocating network resources. The device may determine a quantity of network resources to allocate based on the network policy information, and the device may allocate the quantity of network resources for the UE.

BACKGROUND

An increasing number of long term evolution (LTE) devices are single antenna devices. For example, some devices can support only a single antenna due to size constraints of the devices (e.g., small wearable devices). Additionally, some devices are designed with a single antenna due to cost concerns (e.g., a device such as an electric meter may not need two antennas, and designing the electric meter with one antenna may cut costs). Furthermore, other devices use primarily uplink resources (e.g., a surveillance camera that streams data up to a cloud) and, as a result, do not require more than one downlink antenna.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

For category (CAT) 1 LTE devices and higher, the Third Generation Partnership Project (3GPP) specification defines procedures for dual antenna devices. As a result, a base station (e.g., an evolved Node B (eNB)) may be configured to treat a CAT 1 or higher user equipment (UE) as a dual antenna device. This may cause problems when a base station, communicating with a UE, has to make network resource allocation decisions. For example, CAT 1 or higher devices may be either single antenna UEs or dual antenna UEs, and the base station may be configured to allocate roughly the same amount of network resources to a single antenna UE as a dual antenna UE.

However, if single antenna UEs have less efficient network resource usage (e.g., less spectral efficiency) than dual antenna UEs (e.g., require more network resources to receive the same number of information bits as compared to dual antenna UEs), then a base station may inefficiently allocate network resources to these CAT 1 or higher devices (e.g., by allocating too many network resources to single antenna UEs, and therefore allocating too few network resources to dual antenna UEs). This may waste network resources (e.g., by allocating too many network resources to a particular device), cause unfair allocation of network resources, cause handover (HO) failures (e.g., by allocating too few network resources to a particular device), increase the number of lost connections or dropped calls (e.g., by allocating too few network resources to a particular device), or the like.

Implementations described herein provide one or more network devices with UE antenna information that may be used to create network resource allocation policies and may be further used to generate network resource allocation schedules based on the policies. Additionally, or alternatively, the one or more network devices may be provided with UE device type information that may be used to create network resource allocation policies and schedules (e.g., information indicating the type of device associated with a UE, such as a wearable device type or an internet of things (IoT) device type).

By receiving antenna information and/or device type information, a base station is able to make more intelligent network resource allocation decisions, which conserves network resources by scheduling UEs with resources that are comparable to the particular UE device type. In addition, intelligent network resource scheduling decisions improve user satisfaction and network resource usage by decreasing dropped calls, decreasing handover failures, or the like.

FIGS. 1A and 1B are diagrams of an overview of an example implementation 100 described herein. As shown in FIG. 1A, and by reference number 110, a base station may receive a connection request that includes a UE identifier associated with a UE such as a wearable camera. For example, the UE identifier may be an international mobile equipment identifier (IMEI), and may be sent via a radio resource control (RRC) capabilities exchange during the connection request. As shown by reference number 120, a home subscriber server/authentication authorization and accounting server (HSS/AAA) may obtain antenna information and device type information using the UE identifier. Here, the HSS/AAA may use the IMEI of the UE to access antenna information and device type information in a device management database (DMD). The antenna information may indicate that the UE is a single antenna device. The device type information may indicate that the UE is a wearable camera, and this particular type of wearable camera may be associated with using large quantities of uplink resources and small quantities of downlink resources (e.g., due to the wearable camera being used primarily for uplink streaming).

As shown in FIG. 1B, a policy and charging rules function server (PCRF) may obtain antenna information and device type information from the HSS/AAA. As shown by reference number 130, the PCRF may generate network policy information based on the antenna information and the device type information. The PCRF may send the network policy information back to HSS/AAA, which may send the network policy information to the base station. In this case, the network policy information may include one or more rules relating to the allocation of network resources, and the one or more rules may be associated with the UE being a single antenna device and a wearable camera. As an example, the PCRF may send a policy rule that reduces the quantity of downlink resources available for the UE (e.g., a wearable camera is likely to use a large quantity of uplink resources which may result in the PCRF issuing a policy rule that reduces the quantity of available downlink resources).

As shown by reference number 140, the base station may allocate network resources to the UE based on the network policy information. As an example, a scheduler, of the base station, may use the network policy information to allocate fewer downlink resources to the UE than a typical dual antenna device. By allocating network resources that are comparable to the specific resource needs of the UE (e.g., by allocating just enough resources to satisfy the specific needs of the wearable camera), the base station more effectively allocates overall network resources and increases network capacity.

As indicated above, FIGS. 1A and 1B are provided merely as an example. Other examples are possible and may differ from what was described with regard to FIGS. 1A and 1B. For example, the base station may use the network policy information to allocate network resources for tens, hundreds, or even thousands of UEs.

FIG. 2 is a diagram of an example environment 200 in which systems and/or methods, described herein, may be implemented. As shown in FIG. 2, environment 200 may include a UE 205, a base station 210, an access network 215, a mobility management entity (MME) 220, a serving gateway (SGW) 225, a packet data network (PDN) gateway (PGW) 230, a HSS/AAA 235, a PCRF 240, a DMD 245, and a network 250. Devices of environment 200 may interconnect via wired connections, wireless connections, or a combination of wired and wireless connections.

In some implementations, MME 220 may perform operations relating to authentication of UE 205. Additionally, or alternatively, MME 220 may facilitate the selection of a particular SGW 225 and/or PGW 230 to serve traffic to and/or from UE 205. MME 220 may perform operations associated with handing off UE 205 from a first base station 210 to a second base station 210 when UE 205 is transitioning from a first cell associated with the first base station 210 to a second cell associated with the second base station 210. Additionally, or alternatively, MME 220 may select another MME (not pictured), to which UE 205 should be handed off (e.g., when UE 205 moves out of range of MME 220).

SGW 225 includes one or more network devices capable of routing network traffic. For example, SGW 225 may include one or more data processing and/or traffic transfer devices, such as a gateway, a router, a modem, a switch, a firewall, a network interface card (NIC), a hub, a bridge, a server device, an optical add/drop multiplexer (OADM), or any other type of device that processes and/or transfers traffic. In some implementations, SGW 225 may aggregate traffic received from one or more base stations 210, and may send the aggregated traffic to other network devices. SGW 225 may also receive traffic from other network devices, and may send the received traffic to UE 205 via base station 210.

PGW 230 includes one or more network devices capable of providing connectivity for UE 205 to external packet data networks. For example, PGW 230 may include one or more data processing and/or traffic transfer devices, such as a gateway, a router, a modem, a switch, a firewall, a NIC, a hub, a bridge, a server device, an OADM, or any other type of device that processes and/or transfers traffic. In some implementations, PGW 230 may aggregate traffic received from one or more SGWs 225, and may send the aggregated traffic to network 250. Additionally, or alternatively, PGW 230 may receive traffic from network 250, and may send the traffic to UE 205 via SGW 225 and base station 210. PGW 230 may record data usage information (e.g., byte usage, packet usage, etc.), and may provide the data usage information to HSS/AAA 235.

HSS/AAA 235 includes one or more network devices, such as one or more server devices, capable of managing (e.g., receiving, generating, storing, processing, and/or providing) information associated with UE 205. For example, HSS/AAA 235 may manage information indicating the number of antennas associated with UE 205, information indicating a device type of UE 205 (e.g., a wearable device, an IoT device, a M2M device, etc.), information indicating the network resource requirements associated with UE 205, subscription information associated with UE 205, such as information that identifies a profile of a subscriber associated with UE 205, information that identifies network services and/or applications that are accessible to UE 205, location information associated with UE 205, a network identifier (e.g., a network address) that identifies UE 205, information that identifies a treatment of UE 205 (e.g., quality of service (QoS) information, a quantity of minutes allowed per time period, a quantity of data consumption allowed per time period, etc.), information that identifies whether UE 205 is associated with a radio frequency access signaling usage control policy and/or a radio frequency access signaling usage transaction policy, or the like. HSS/AAA 235 may provide this information to one or more other devices of environment 200 to support the operations performed by those devices.

Additionally, or alternatively, HSS/AAA 235 includes one or more devices, such as one or more server devices that perform authentication, authorization, and/or accounting operations for communication sessions associated with UE 205. For example, HSS/AAA 235 may perform authentication operations for a subscriber associated with UE 205 (e.g., using one or more credentials), may control access, by UE 205, to a service and/or an application (e.g., based on one or more restrictions, such as time-of-day restrictions, location restrictions, single or multiple access restrictions, read/write restrictions, etc.), may track resources used by UE 205 (e.g., a quantity of voice minutes used, a quantity of data used, a quantity of radio frequency signals transmitted, a quantity of radio access bearers requested and/or established, etc.), and/or may perform similar operations.

PCRF 240 includes one or more network devices, such as one or more server devices, capable of providing network policies and rules relating to antenna information and/or device type information. Policies and rules regarding antenna information and/or device type information may include policies and rules indicating network resource requirements associated with UEs 205 based on, for example, the number of antennas the UEs 205 have and/or the device types of the UEs 205. In addition, PCRF 240 may provide network control regarding service data flow detection, gating, QoS, and/or flow-based charging. Policies and rules regarding QoS may include policies and rules instructing UE 205 and/or network devices (e.g., base station 210, SGW 225, PGW 230, etc.) to minimize packet loss, to implement a packet delay budget, to provide a guaranteed bit rate (GBR), to provide a particular latency, to reduce radio frequency (RF) signal congestion, and/or to perform other activities associated with QoS. PCRF 240 may provide policies and rules to other network devices, such as base station 210, SGW 225, PGW 230, or the like, to implement network control. PCRF 240 may determine how a certain service data flow shall be treated, and may ensure that subscriber plane traffic mapping and QoS is in accordance with a subscriber's profile and/or network policies.

In some implementations, DMD 245 may receive, from HSS/AAA 235, a DMD query (e.g., to determine antenna information associated with UE 205) based on a UE 205 identifier, and may compare the DMD query to the database of antenna information. Based on the query, DMD 245 may provide antenna information back to HSS/AAA 235.

FIG. 4 is a flow chart of an example process 400 for allocating network resources to a device. In some implementations, one or more process blocks of FIG. 4 may be performed by base station 210. In some implementations, one or more process blocks of FIG. 4 may be performed by another device or a group of devices separate from or including base station 210, such as UE 205, MME 220, SGW 225, PGW 230, HSS/AAA 235, PCRF 240, or DMD 245.

As shown in FIG. 4, process 400 may include receiving antenna information indicating that a user equipment (UE) has a single antenna (block 410). In some implementations, base station 210 may receive antenna information, from UE 205, indicating that UE 205 includes a single antenna. Additionally, or alternatively, base station 210 may receive antenna information, indicating that UE 205 includes a single antenna, from a network device, such as MME 220, HSS/AAA 235, PCRF 240, or DMD 245.

In some implementations, base station 210 may receive antenna information from UE 205 during or after a connection request. As an example, UE 205 may send antenna information to base station 210, during a connection request, indicating that UE 205 is a single antenna device. During the connection request, UE 205 and base station 210 may participate in a RRC capabilities exchange where UE 205 may send (e.g., as a parameter in the RRC capabilities exchange) antenna information to base station 210. Base station 210 may send the antenna information to another network device (e.g., HSS/AAA 235, PCRF 240, DMD 245, etc.), and the other network device may use the antenna information to create and store policies regarding the allocation of network resources, as described further herein.

In some implementations, base station 210 may receive antenna information from another network device. For example, HSS/AAA 235 and/or DMD 245 may store antenna information and may send the stored antenna information to base station 210. HSS/AAA 235 and/or DMD 245 may store the antenna information in a way that indicates a relationship between a UE identifier (e.g., an IMEI, an international mobile subscriber identity (IMSI), a subscriber identity module (SIM), an integrated circuit card identifier (ICCID), etc.) and antenna information associated with UE 205.

As an example, base station 210 may receive, from HSS/AAA 235, antenna information indicating that UE 205 is a single antenna device. In this case, during or after UE 205 connects to base station 210, UE 205 may send base station 210 a UE identifier, and base station 210 may send the UE identifier to HSS/AAA 235. HSS/AAA 235 may use the UE identifier to access the antenna information (e.g., information indicating that UE 205 is a single antenna device) in a subscriber profile associated with UE 205, and HSS/AAA 235 may send the antenna information to base station 210.

As another example, base station 210 may receive, from DMD 245, antenna information indicating that UE 205 is a single antenna device. In this case, during or after UE 205 connects to base station 210, UE 205 may send base station 210 a UE identifier, and base station 210 may send the UE identifier to HSS/AAA 235. HSS/AAA 235 may use the UE identifier to access antenna information stored by DMD 245. For example, HSS/AAA 235 may use the UE identifier as a search query, and the search query may be used to locate a record, stored by DMD 245, that has a matching UE identifier along with corresponding antenna information (e.g., antenna information indicating that UE 205 is a single antenna device). HSS/AAA 235 may send the antenna information to base station 210. By providing base station 210 with information indicating that UE 205 is a single antenna device, base station 210 is able to make more intelligent network resource allocation decisions, as described further herein.

As further shown in FIG. 4, process 400 may include receiving device type information indicating a device type of the UE and/or network resource requirements associated with the UE (block 420). Device type information may indicate a type of device (e.g., a wearable device, an IoT device, an M2M device, a device with a sensor, an uplink-centric device such as a device that consumes primarily uplink resources, etc.), and/or may indicate network resource requirements associated with UE 205 (e.g., a device application may be associated with a certain range of per day data-byte consumption, an amount of throughput, an amount of latency, an amount of jitter, a level of QoS, etc.). Device type information may be received alone, or in conjunction with, the antenna information described above.

In some implementations, base station 210 may receive, from UE 205, device type information indicating a device type of UE 205. As an example, during a connection request from UE 205, base station 210 may receive device type information indicating that UE 205 is a wearable device. During the connection request, UE 205 and base station 210 may participate in a RRC capabilities exchange where UE 205 may send (e.g., as a parameter in the RRC capabilities exchange) the device type information to base station 210. Base station 210 may send the device type information to another network device (e.g., HSS/AAA 235, PCRF 240, DMD 245, etc.), and the other network device may use the device type information to create and store policies regarding the allocation of network resources, as described further herein.

Additionally, or alternatively, base station 210 may receive, from UE 205, device type information indicating network resource requirements associated with UE 205. As an example, during or after a connection request from UE 205, base station 210 may receive device type information (e.g., UE 205 may be a wearable camera) indicating that the device type of UE 205 is associated with using a low amount of downlink resources per day (e.g., a wearable camera may use a low amount of downlink resources because wearable cameras are used primarily for uplink streaming).

Additionally, or alternatively, base station 210 may receive, from UE 205, a UE identifier, and base station 210 may use the UE identifier to obtain information indicating network resource requirements associated with UE 205. As an example, during or after a connection request from UE 205, base station 210 may receive a UE identifier, and base station 210 may use the UE identifier to obtain information indicating network resource requirements associated with UE 205. In some cases, base station 210 may use the UE identifier as a search query, and the search query may be used to locate a record, stored by a network device (e.g., HSS/AAA 235, DMD 245, etc.), that has a matching UE identifier, along with corresponding information indicating the network resource requirements associated with UE 205. In other cases, base station 210 may use the UE identifier to access a local data structure that stores the UE identifier with corresponding network resource requirements associated with UE 205. Base station 210 may also obtain network resource requirements associated with UE 205 by receiving, from UE 205, information indicating a type of device of UE 205 (e.g., during a connection request), and may access the information in the same manner described above.

In some implementations, base station 210 may receive, from a network device such as HSS/AAA 235 or DMD 245, device type information indicating a device type of UE 205. As an example, a subscriber profile of UE 205 (e.g., stored by HSS/AAA 235) may include information indicating that UE 205 is a wearable device. In this case, when UE 205 sends a UE identifier to base station 210, base station 210 may send the UE identifier to HSS/AAA 235, and HSS/AAA 235 may use the UE identifier to access the information indicating that UE 205 is a wearable device. As another example, the device type information may be stored by DMD 245, and accessed by HSS/AAA 235, as described above.

Additionally, or alternatively, base station 210 may receive, from a network device such as HSS/AAA 235 or DMD 245, device type information that indicates network resource requirements associated with UE 205. As an example, a subscriber profile of UE 205 (e.g., stored by HSS/AAA 235) may include information indicating that UE 205 uses primarily uplink resources (e.g., UE 205 may be a wearable camera used primary for uplink streaming). In this case, when UE 205 sends a UE identifier to base station 210, base station 210 may send the UE identifier to HSS/AAA 235, and HSS/AAA 235 may use the UE identifier to access device type information indicating that UE 205 is a wearable camera that uses primarily uplink resources. As another example, the device type information may be stored by DMD 245 and accessed by HSS/AAA 235, as described above. By providing base station 210 with information indicating the device type and/or the network resource requirements associated with UE 205, base station 210 intelligently allocates network resources.

As further shown in FIG. 4, process 400 may include obtaining network policy information relating to the UE based on the antenna information and/or the device type information (block 430). For example, base station 210 may obtain network policy information relating to UE 205 from one or more network devices (e.g., MME 220, SGW 225, PGW 230, HSS/AAA 235, PCRF 240, and/or DMD 245), and the network policy information may be based on the antenna information and/or the device type information of UE 205. Network policy information may include information indicating one or more policy rules that may be used to allocate network resources to UE 205.

In some implementations, prior to base station 210 obtaining the network policy information, PCRF 240 may use the antenna information and/or the device type information to generate the network policy information. For example, PCRF 240 may access antenna information and/or device type information stored by a network device such as HSS/AAA 235 and/or DMD 245, and PCRF 240 may use the antenna information and/or device type information to generate one or more policy rules that allocate network resources to UE 205. PCRF 240 may generate one or more policy rules, for example, by monitoring the network resources that UEs 205 of a particular device type consume during a given time period. As an example, PCRF 240 may monitor a volume of network traffic that UEs 205 of a particular device type consume during a given time period. In this case, PCRF 240 (or a different network device such as HSS/AAA 235 and/or DMD 245) may store information indicating the network traffic consumed by the UEs 205, during the given time period, with corresponding antenna information and/or device type information. PCRF 240 may send this information to base station 210, and base station 210 may use the one or more policy rules to allocate network resources to UE 205, as described further herein.

In some implementations, PCRF 240 may generate policy rules that indicate a situation where base station 210 may reduce a quantity of network resources available for UE 205 (e.g., a policy rule may indicate a situation where base station 210 may reduce a quantity of uplink resources and/or reduce a quantity of downlink resources, a policy rule may indicate a situation where base station 210 may reduce a quantity of network resources based on a time restriction, a policy rule may indicate a situation where base station 210 may reduce a quantity of network resources based on a device priority level, etc.). Additionally, or alternatively, PCRF 240 may generate policy rules that indicate a situation where base station 210 may increase a quantity of network resources available for UE 205 (e.g., a policy rule may indicate a situation where base station 210 may increase network resources based on one or more QoS parameters, a policy rule may indicate a situation where base station 210 may increase network resources based on a degree of mobility of a device, a policy rule may indicate a situation where base station 210 may increase network resources based on one or more exception conditions, such as a critical condition that requires allocating additional network resources to a device when the critical condition is satisfied, etc).

In some implementations, base station 210 may obtain, from the one or more network devices, network policy information for UE 205 that indicates one or more policy rules. As an example, one or more policy rules may be associated with UE 205 being a single antenna device such as a smart meter. In this case, the one or more policy rules may include a policy rule that reduces a quantity of available network resources during periods of heavy network traffic (e.g., a quantity of network traffic that satisfies a threshold). This policy rule may be created for a device type such as a smart meter because smart meters may be configured to transmit data during set intervals, and changing the transmission interval may be done without any major consequence (e.g., whether a smart meter transmits data at 6:00 PM or 11:00 PM may not matter if a user is not checking the data until the following day). As a result, base station 210 may reduce network resources available to the smart meter during periods of heavy network traffic, thereby conserving overall network resources and maximizing operating efficiency of the network.

As another example, base station 210 may obtain one or more policy rules associated with UE 205 being a single antenna device such as a wearable camera. In this case, the one or more policy rules may include a rule that provides for a reduced quantity of downlink resources, while providing for restriction-free use of uplink resources. This policy rule may be created for a device type such as the wearable camera because wearable cameras are used primarily for uplink streaming. As a result, base station 210 may reduce downlink resources without restricting the uplink resources needed for the wearable camera to stream data.

As another example, base station 210 may obtain policy rules associated with UE 205 being a single antenna device such as a M2M/IoT security system. In this case, the one or more policy rules may include a rule that reduces a quantity of network resources associated with non-VoLTE transmissions, while providing for restriction-free use of VoLTE in case of an emergency (e.g., the security system may need to make a VoLTE call to report a crime). By obtaining policy rules associated with the antenna information and the device type of UE 205, base station 210 is able to make more efficient network resource allocation decisions.

Additionally, or alternatively, PCRF 240 may generate models which are trained using artificial intelligence or machine learning, and the models identify policy rules based on the antenna information and/or the device type information. For example, assume PCRF 240 monitors and stores the antenna information and/or the device type information of UEs 205 that connect to a network (this may be tens, hundreds, or even thousands of UEs 205). PCRF 240 may use the antenna information and/or the device type information to generate models that are able to predict a quantity of resources to allocate to a particular UE 205 based on the network resources used by UEs 205 that share the same number of antennas or that share the same device type.

As an example, PCRF 240 may generate a model using antenna information and/or device type information of UEs 205 that connect to a network (e.g., over a given time period). In this case, the model may, for different groups of UEs 205 (e.g., where a group of UEs 205 is associated with a particular combination of device type information and/or antenna information), include information indicating a range of network resources consumed by the groups of UEs 205. The model may be trained in real-time (e.g., relative to a UE 205 connecting to the network), or PCRF 240 (or another network device such as HSS/AAA 235 and/or DMD 245) may store the model for later use.

As further shown in FIG. 4, process 400 may include allocating network resources for the UE based on the network policy information (block 440). For example, a scheduler of base station 210 may allocate network resources based on the network policy information. The scheduler of base station 210 may allocate network resources for UE 205 by using one or more scheduling algorithms to determine one or more network resource limitations and/or one or more time limitations associated with UE 205 (e.g., a network resource limitation may be a quantity of network resources to allocate to UE 205, and a time limitation may be a time period where UE 205 may use the quantity of network resources). In some implementations, base station 210 may determine the one or more network resource limitations and/or the one or more time limitations for UE 205 by considering the network policy information, the antenna information, and/or the device type information. Additionally, or alternatively, base station 210, when allocating network resources to UE 205, may consider network traffic associated with other UEs 205 and/or priority information associated with other UEs 205.

As an example, base station 210 may receive a request to connect to a network from a single antenna device such as a smart meter. Assume that, at this same time, base station 210 is receiving heavy network traffic from a group of dual antenna devices and/or other single antenna devices. Further assume that the network policy information associated with UE 205 includes a policy rule for allocating a reduced quantity of network resources to the smart meter during periods of heavy network traffic. Due to heavy network traffic, base station 210 may execute a scheduling algorithm that allocates a reduced quantity of network resources to the smart meter based on the policy rule. By reducing the quantity of network resources available for UE 205 during periods of heavy network traffic, base station 210 efficiently allocates network resources in a way that reduces network congestion.

As another example, base station 210 may receive a request to connect to a network from a single antenna device such as a wearable camera. Assume that, at this same time, base station 210 may also be receiving traffic from a group of dual antenna devices and/or single antenna devices. Further assume that the network policy information associated with UE 205 may include a policy rule for allocating a reduced quantity of downlink resources (e.g., due to the wearable camera being used primarily for uplink streaming). Next, base station 210 may execute a scheduling algorithm that allocates a reduced quantity of downlink resources to UE 205 based on the policy rule. By reducing the quantity of network resources available to UE 205, base station 210 frees up additional network resources for other network devices (e.g., such as other UEs 205).

As another example, base station 210 may receive a request to connect to a network from a single antenna device such as a security camera. Assume that, at this same time, base station 210 may also be receiving traffic from a group of dual antenna devices and/or a group of other single antenna devices. Further assume that the network policy information associated with UE 205 may include a policy rule for allocating a reduced quantity of network resources to UE 205 for non-VoLTE transmissions (e.g., without restricting the network resources available for VoLTE transmissions in case the security camera needs to report a crime). Next, base station 210 may execute a scheduling algorithm that allocates a reduced quantity of network resources to UE 205 for non-VoLTE transmissions. By allocating network resources based on antenna information and device type information, base station 210 conserves overall network resources, and improves network resource usage by decreasing dropped calls, reducing handover failures, or the like.

In some implementations, base station 210 may allocate and reallocate network resources for UEs 205 using one or more scheduling algorithms that consider the network resource needs of the UEs 205 during a particular time period (e.g., a period with network congestion, a period without network congestion, etc.). For example, base station 210 may allocate network resources to a group of single antenna UEs 205, and base station 210 may subsequently decrease a quantity of network resources available for the group of single antenna UEs 205 during periods of network congestion. As an example, base station 210 may decrease a quantity of network resources available for a group of single antenna UEs 205 if new devices connect to the network and cause network congestion. By allocating fewer resources to single antenna UEs 205 during a period of network congestion, base station 210 is able to allocate additional network resources to dual antenna UEs 205 that connect to the network, and this may decrease the number of dropped calls and handover failures associated with those devices.

In some implementations, base station 210 may monitor single antenna devices separately from dual antenna devices. In this case, base station 210 may be able to detect technical problems or deficiencies that are specific to single antenna devices and may send information indicating key performance indicators (KPIs) to one or more network devices who may perform preventative and/or restorative actions. In this way, base station 210 makes additional resource-saving decisions based on the network policy information.

Although FIG. 4 shows example blocks of process 400, in some implementations, process 400 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in FIG. 4. Additionally, or alternatively, two or more of the blocks of process 400 may be performed in parallel.

By providing one or more network devices with antenna information and/or device type information, base station 210 is able to make more intelligent network resource allocation decisions (e.g., by allocating UEs 205 with resources that are comparable to the particular device type of UE 205). In addition, the intelligent network resource scheduling decisions improve user satisfaction and network resource usage by decreasing dropped calls, decreasing handover failures, or the like.
